Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Starrag. Configuration moves it a long way.
Overview
The Starrag NB Series is a family of 5-axis machining centers with a turning function. Starrag's series page states little in figures, and this page follows it: an HSK-T100 spindle taper, displacement and temperature sensors in the spindle, and a surface finish capability of Ra < 0.6 um.
The taper says the most about the machine. HSK-T100 is a large interface, and the T form is the version of HSK intended for turning tools as well as rotating ones. That fits the axis count Starrag gives: 5, with turning. A part that needs both milled surfaces and turned diameters can be finished without a second machine and without a second clamping error.
The sensors measure spindle displacement and temperature, the two things that move a tool tip during a long cut. A finish figure of Ra < 0.6 um indicates the series is aimed at surfaces that are left as machined. Travels, speeds, power, part weight and tool capacity do not appear on the series page, so sizing a machine from this family starts with a request to Starrag for the data of the individual model.

Strengths & Limitations
Strengths
- HSK-T100 spindle taper, a large interface in the form intended for turning tools as well as milling tools
- 5 axes with turning, so milled and turned features are cut on one machine
- Displacement and temperature sensors in the spindle
- Surface finish capability listed at Ra < 0.6 um
Limitations
- The series page gives no travels, spindle speed, power or tool capacity
- No workpiece size or weight limit is stated, so part fit cannot be checked from the page

Frequently Asked Questions
01
HSK-T100. It is a large taper, and the T form of HSK is the one intended for turning tools as well as rotating tools. The spindle is also fitted with displacement and temperature sensors.
02
Yes. Starrag lists the number of axes as 5, with turning, and the HSK-T100 taper suits turning tools. Milled and turned features can therefore be finished on the same machine.
03
The series page states the spindle taper (HSK-T100), the spindle sensors (displacement and temperature), the axis count (5, with turning) and a surface finish capability of Ra < 0.6 um. It gives no travels, speeds, power or tool capacity.
